Rolls R48-100LFP ESS Battery Installation

Modified on Mon, 29 Jun at 10:49 AM

INSTALLATION

Rolls R48-100LFP ESS rack-mount batteries are compatible with standard 19” rack hardware.

The battery may be installed horizontally or vertically.

Note: Only trained electrical power system technicians (or equivalent) should install the battery system. Before installing or removing the battery, make sure that the system is disconnected from any power source and that each battery module is turned off. Distribution cabling needs to be handled carefully with reasonable protective measures to avoid shorting or inadvertent connections during maintenance and operation.

Note : Seuls les techniciens qualifiés en systèmes d'alimentation électrique (ou équivalent) devraient installer le système. Avant d'installer ou de retirer la batterie, assurez-vous que le système est déconnecté de toute source d'alimentation et que chaque batterie est éteint. Le câblage de distribution doit être manipulé avec soin et des mesures de protection raisonnables doivent être prises pour éviter les courts-circuits ou les connexions involontaires pendant la maintenance et le fonctionnement.

PARALLEL BATTERY ESS INSTALLATION

Rolls R48-100LFP ESS batteries may be combined in parallel to increase system capacity and power delivery. Rolls R48-100LFP ESS batteries can support up to 32 battery modules in parallel.

R48-100LFP ESS
Single Battery Operation
State of Charge (SOC)	0-4%	4-20%	20-95%	95%-100%
Constant Voltage Limit (CVL)	56V	56V	56V	56V
Constant Current Limit (CCL)	30A	70A	100A	20A
Discharge Current Limit (DCL)	0	50A	100A	100A
N-module ESS Operation
State of Charge (SOC)	0-4%	4-20%	20-95%	95%-100%
Constant Voltage Limit (CVL)	56V	56V	56V	56V
Constant Current Limit (CCL)	30A*N	70A*N	100A*N	20A*N
Discharge Current Limit (DCL)	0	50A*N	100A*N	100A*N

Note: BMS will also automatically derate the battery (lower the requested charge and discharge currents) at the extremes of the temperature range, to protect the cells.

Note: The closed-loop charge and discharge currents provided above are intended to represent design maximums for your system. Designing your system around limiting discharge rate to ≤ 0.5C will maximize system life, however the BMS will not limit you to this operating condition.

Note: Refer to the Communication Interface section for the parallel communication cable connections.

CABLE CONNECTION

All external cable connections should be adequately sized, insulated, and undamaged. The cable connectors should be clean and properly mated with the battery terminals to ensure a snug connection. Terminal connections should be torqued to the recommended specification below. Although Rolls R48-100LFP ESS batteries do not require maintenance, routine inspection of cabling and terminal connections is recommended.

AMPERAGE	25	30	40	55	75	95	130	150	170	195	260
WIRE GAUGE	14	12	10	8	6	4	2	1	1/0	2/0	4/0

Note: Undersized cables may lead to cable and/or battery damage, charging issues, terminal heating, or fire. The above table is only meant to provide a quick reference, ALWAYS consult with the manufacturer’s specification for conductor current and temperature.

TERMINAL TORQUE

Terminal connections must be properly torqued. Rolls batteries using M6 fasteners should be torqued to 4-6 Nm.

DO NOT OVERTORQUE: If a terminal is damaged, do not attempt to repair the terminal. Do not use the battery if the recommended torque specification cannot be met.
